This week’s On the Radio segment looks at a recent report that shows Iowa farmers are increasingly turning to environmentally friendly soil conservation practices. Listen to the audio below, or continue reading for the transcript.

Transcript: Soil Conservation

Cover crops, crop rotation, and other soil conservation practices are gaining in popularity with Iowa farmers, according to a recent report.

This is the Iowa Environmental Focus.

The international consulting firm Datu Research released the 53-page report in December which found that 23 percent of those surveyed reported that they planted cover crops on their farms. Eighty percent of respondents said they alternate their fields between corn and soybeans each year while 70 percent of farmers said they practice minimum or conservation tilling practices.

These techniques improve soil health and help to regulate moisture content. This allows soil to retain more nitrate and phosphorus, saving farmers on fertilizer costs while also reducing nutrient runoff which is a major cause of water pollution in Iowa.

Agricultural runoff accounts for approximately 70 percent of the nitrogen and phosphorus that enters the Gulf of Mexico through the Mississippi River.

Dam modifications may revitalize Iowa rivers

Dam removal or modification projects may bring improved fishing and recreation to some eastern Iowa rivers.

Several projects along the Cedar, Wapsipinicon, Maquoketa and Turkey Rivers aim to repeat the success of a white-water course opened on the Cedar River in Charles City in 2011 and a rock arch rapids project opened in the Turkey River in 2010. Rock arch rapids simulate natural rapids using re-engineered or modified low-head dams, many of which have deteriorated over time and were previously not passable for aquatic life, canoes and kayaks.

In addition to becoming new destinations for kayaks and canoes, these projects also remove barriers to fish migration and improve recreational safety. The projects may prevent tragedies like a tubing accident at a low-head dam that claimed one life in the summer of 2014.

The Iowa Legislature recently increased its annual budget for small-scale dam removal and water trails to $2 million, according to a recent report in The Gazette.

Proposed oil pipeline would run through 17 Iowa counties – An 1,100-mile oil pipeline was proposed to run from Lyon County in the northwest corner of Iowa to Lee County in the southeast.

Ottumwa meat plant is Iowa’s top waterway polluter – A report that showed, among other concerns, that one Iowa meat plant dumped three million pounds of chemicals into the Lower Des Moines River in 2012.

Iowa’s Allamakee county looks to implement nation’s strictest fracking ordinance – In June, the Allamakee County (Iowa) Board of Supervisors voted 3-0 to approve what looks to be “the most strict frac sand mining ordinance in the nation.”

Hemp advocates announce 6th Annual Hemp History Week – This event, taking place in 2015, aims to bring attention to hemp as an environmentally sustainable crop with both nutritional and medical uses.

This week’s On the Radio segment looks at a new initiate to mitigate the effects of climate change on Iowa farmers. Listen to the audio below, or continue reading for the transcript.

Transcript: Agriculture and Climate Change

A North American farm group is taking proactive steps to reduce the effects of climate change on agriculture.

This is the Iowa Environmental Focus.

The group – Solution from the Land – is supporting the North American Climate Smart Agriculture Initiative. The initiative aims to bring together representatives from industry and academia as well as government and non-government organizations in an effort to mitigate the effects of climate change for farmers.

The initiative follows the release of the National Climate Statement which suggests that at its current rate, the effects of climate change will be largely detrimental to crops and livestock over the next 25 years. The initiative aims to help farmers adapt to changes in precipitation and temperature.

The American Farm Bureau Federation, the American Soybean Association, and the National Farmers Union are some of the national organizations which have endorsed the effort.

Dubuque recognized for efforts to address climate change

Nick Fetty | December 9, 2014

Dubuque, Iowa was among 15 other local and tribal communities to be named Climate Action Champions by the White House last week.

Dubuque was recognized because of its Community Climate Action & Resiliency Plan which has set a greenhouse gas reduction goal of being 50 percent below 2003 levels by 2030. The plan – which examined Dubuque from 2003 to 2011 – traced emissions to four main sources: industrial (31%), residential (24%), transportation (23%), and commercial (17%), with the remaining 5 percent coming from the landfill methane.

The city hopes to further offset carbon emissions by further utilizing renewable energy sources. The report states that “solar and wind installations in Dubuque are expected to yield 10,000-30,000 mt (metric tonnes) of annual reductions by 2030.” Wind energy and other renewables generated 18 percent of electricity in Dubuque during the study in 2010.

In addition to efforts to curb greenhouse gas emissions, Dubuque was also honored because of the city’s emphasis on flood-conscious infrastructure. Flooding on the Mississippi River has caused Dubuque to be declared a presidential disaster zone six times in the last 16 years so the city is now focused on mitigation efforts.

The Bee Branch Watershed Flood Mitigation Project is a $179-million project that will focus on a 6.5 square mile district where more than half of the city’s population lives or works. The project aims to “both reduce the volume and slow the rate of stormwater in the upper watershed, provide safer conveyance of stormwater in flood-conducive areas, and protect the City’s wastewater treatment plant from stormwater.” Construction is expected to begin fall 2015 and be completed by 2016.

The Climate Action Champions were selected by representatives from the Department of Energy.

On the Radio: New rule to curb agricultural pollution

This week’s On the Radio segment looks at a new measure that provide stricter enforcement of rules against manure spills. Listen to the audio below, or continue reading for the transcript.

Transcript: New Rule

A new rule to curb agricultural pollution in Iowa waterways is now in effect.

This is the Iowa Environmental Focus.

The Iowa Department of Natural Resources, as part of a deal with the U.S. Environmental Protection Agency, has developed a new measure which will provide stricter enforcement of rules against manure spills on livestock farms. More than 60 such spills have been reported over the last year, which have caused contamination leading to fish kills and water pollution.

The DNR is poised to inspect farms’ handling of manure more stringently, issuing fines to operations that don’t cooperate. Earlier this year, a dairy farm was ordered to pay over $160,000 for a spill that killed hundreds of thousands of fish in a nearby lake.

Iowa farms produce waste from 60 million chickens, 20 million pigs, 9 million turkeys, and 4 million cows.
